In theory, since my 54 birds are all adults, they are expected to eat about 1/4# each a day, the pekin ducks twice that, effectively 64 birds and a total of 16# per day (expected/predicted). During winter with my pasture, I was able to feed 13- 14#/day w/o them getting too fat or too thin. Currently, I'm feeding 10# a day. It helps, but this is about as good as it gets for me with my current pasture. Based on their behaviors, I may be able to cut to 9#/day, I need to cull a couple for table and check their condition internally.
and I'm collecting 30-32 eggs a day, plus 4-5 duck eggs, but most of my birds are hens.
And always interested in ways I can do it better.
